Annular Massage Head Motion for Expanded Stimulation Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sex toys have a limited stimulation range and unsatisfactory stimulation effect, failing to provide comprehensive and comfortable sexual experiences.
Innovation Solution
A massage device with a shell that allows for insertion into the human body, featuring a moving space that enables the first massage portion to move along an annular trajectory under the drive of the first driving unit, enhancing the stimulation range and effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a motor drives the massage head to do linear reciprocating motion, then the device structure is simple, but the stimulation range is limited and stimulation effect is unsatisfactory
Solution Approach 1:
The massage head is transformed from linear reciprocating motion to annular trajectory motion, adding a rotational dimension to the movement. This dimensional change allows the massage head to cover a larger area of the vaginal wall, expanding the stimulation range while maintaining a relatively simple device structure through the use of a crank mechanism.
Solution Approach 2:
The massage head motion is changed from simple linear reciprocating motion to dynamic annular trajectory motion. This dynamic movement pattern enables the massage head to knead and stimulate different areas of the vaginal wall more effectively, improving the stimulation effect while the crank mechanism keeps the overall device structure manageable.
2Device complexity
If a motor drives the massage head to do linear reciprocating motion, then the device structure is simple, but the stimulation effect is unsatisfactory
Solution Approach 1:
The massage head motion is changed from simple linear reciprocating motion to dynamic annular trajectory motion. This dynamic movement pattern enables the massage head to knead and stimulate different areas of the vaginal wall more effectively, improving the stimulation effect while the crank mechanism keeps the overall device structure manageable.
Solution Approach 2:
The massage head moves along an annular (circular) trajectory instead of a straight line, utilizing curved motion to better conform to the anatomical structure of the vaginal wall. This curved path allows for more effective kneading and stimulation of the tissue, enhancing the overall stimulation effect.
3Area of stationary object
If the massage portion moves along an annular trajectory, then the stimulation range is enlarged and stimulation effect is improved, but the device complexity increases
Solution Approach 1:
The massage head is transformed from linear reciprocating motion to annular trajectory motion, adding a rotational dimension to the movement. This dimensional change allows the massage head to cover a larger area of the vaginal wall, expanding the stimulation range while maintaining a relatively simple device structure through the use of a crank mechanism.
Solution Approach 2:
A crank mechanism is introduced as an intermediary component to convert the motor's rotational motion into the annular trajectory motion of the massage head. This intermediary mechanism enables the complex motion pattern while keeping the overall device structure manageable by using a well-established mechanical principle.

AI summary
A massage device includes a shell, a first massage portion and a first driving unit. The shell is configured to be inserted into a human body along an insertion direction. A moving space is defined in a middle portion of the shell in the insertion direction and extends through a lateral wall of the shell to define an opening therein. The moving space communicates with an external environment out of the shell through the opening of the lateral wall of the shell. The first massage portion extends into the moving space of the shell. The first driving unit is arranged in the shell and connected to the first massage portion. Under the driving of the first driving unit, the first massage portion moves along an annular trajectory.
